MPG larger than AVI??

[sjmaye]

I took a 528x400AVI and encoded it to a 720x480 MPG. I would have thought the mpg would be smaller due to compression. Is the reason the MPG is larger that I was going up to 720x480?

I've had similar results.
I tried to convert a 50mb (taken from my canon digital camera - 30 seconds video) to mpeg and the converted file was 70mb. I don't understand.
I am trying to shrink that avi file to as small as possible to email as attachement.
Any clues or help?
Thanks

AVI is a container and may have video and audio compressed with any number of codecs. In all likelihood your AVI file had MPEG4 (Divx/Xvid) video that is much more compressed than MPEG. Not only that but you enlarged the frame which requires even more bitrate.

The file size is determined by two things: the running time times the bitrate. If you want a smaller file use a lower bitrate. Of course, the lower the bitrate, the less the quality.

Scropion, It doesn't hurt to have two people's feedback.

You said what I was going to say, only better.

Good luck everyone, and have a good weekend.
